HBN-encapsulated, graphene-based room-temperature terahertz receivers with high speed and low noise
Leonardo Viti, David G. Purdie, Antonio Lombardo +2
Uncooled Terahertz (THz) photodetectors (PDs) showing fast (ps) response and high sensitivity (noise equivalent power (NEP) < ) over a broad (0.5THz-10THz) frequency r…
Graphene/Polyelectrolyte Layer-by-Layer Coatings for Electromagnetic Interference Shielding
Cristina Valles, Xiao Zhang, Jianyun Cao +7
Electromagnetic interference (EMI) shielding coating materials with thicknesses in the microscale are required in many sectors, including communications, medical, aerospace and ele…
Screen-printed and spray coated graphene-based RFID transponders
K. Jaakkola, V. Ermolov, P. G. Karagiannidis +7
We report Ultra-High-Frequency (UHF, 800MHz-1GHz) Radio Frequency Identification (RFID) transponders consisting of printed dipole antennas combined with RFID microchips. These are…
Graphene Reflectarray Metasurface for Terahertz Beam Steering and Phase Modulation
Michele Tamagnone, Santiago Capdevila, Antonio Lombardo +6
We report a THz reflectarray metasurface which uses graphene as active element to achieve beam steering, shaping and broadband phase modulation. This is based on the creation of a…
